Thunderstone Search Appliance Manual

In the past, when a profile was restored
from backup, it was not actually scheduled with the profile's rewalk schedule
setting. This has been fixed, but customers that had restored profiles
using old software may still have profiles in this state.

The Re-schedule walks section confirms that all profiles' schedules match
their rewalk schedule settings, and allows the re-application all profile's
scheduled settings to the walk scheduler. Not normally needed.
